Abstract
An electronic detonator control chip () includes a communication interface circuit (), a rectification bridge circuit (), a charging circuit (), a charging control circuit (), a power management circuit (), a firing control circuit (), a logic control circuit (), a non-volatile memory (), a reset circuit (), a safe discharging circuit (), and a clock circuit (). Wherein, the communication interface circuit () includes a data modulation module () and a data demodulation module () including two data demodulation circuits (). The logic control circuit () further includes a programmable delay module (), an input/out interface (), a serial communication interface (), a prescaler (), a CPU (), and so on. Therefore, the electronic detonator control chip provided by the invention enables to realize the functions of two-wire non-polarity connection, bidirectional communication with a detonation equipment external of the electronic detonator control chip, ID card inside the detonator, control of the detonation process and online program of the delay time and so on.
